I got unusual errors occasionally for an rl nic and the machine randomly rebooted. Sometimes nothing was logged. It turned out to be the network card. I replaced the NIC with a 3com 3c905c TX and the problem went away. Its possible that the dell NICs are non standard and the driver isn't handling them well. I've noticed problems with dell nics and standard drivers in their other products (lattitude d800, etc). If you really thought it was an SMP issue, I suppose you could compile and run a non smp kernel as a test. Its also possible that "4" processor smp isn't as reliable as 2. I have read about scalability issues in the past with large numbers of cpus in freebsd.
